"Rea Professional Contracting did an outstanding job remodeling our bathroom. We did a full remodel of everything, down to the studs. Their work is exceptional. We had to be out-of-town for a few days considered cancelling our trip. No need; Rea treated our house as if it was their own. They cleaned up nightly and were very respectful our privacy and the fact that we were "living" here while they were working. Would happily recommend them to anyone without hesitation."

"A long over due review. From the initial consultation to the jobs end. Extremely seamless. We had our kitchen remodeled and ton of extras we threw at him. Jose from day one was extremely professional from start to finish and takes pride in his work. So you can expect perfection on finish work. Alta gave us a fair priced estimate and a very detailed estimate of scope of work from start to finish. No surprise charges. The work was done in a timely fashion and completed on the timeline set forth. We were and are very happy with the quality of work and the professionalism throughout the project. Jose and Alta Renovations will be hired by us again to do our bathroom. I am attaching a link to the finish project below [*** Link removed ***]"

Customers say: True professional

"Arthur gave us a fair and competitive estimate and was able to start work quickly thereafter. He and his team did an excellent job gutting and totally remodeling two bathrooms and a closet as well as redoing some of the wood flooring, moving vents, and moving hallways. Arthur himself was at the home everyday and did the important work himself. He also went the extra mile in helping us with small projects around the major project as they came up. He was extremely responsive in provided us with timely updates. When complications occurred (due to the house having not been renovated in 40 years) he was clear and helpful in keeping the project on schedule. He was extremely honest and I trusted him to be alone in my house for weeks on end with his team. I would/plan to work with Arthur again in the future for my home renovation projects."

"The handy men were really nice and respectful. They did 2 jobs for me which includes a tv set with a fire place and a bead board for my California king size bed. The job was done in 3hrs and the work was done sufficiently. They cleaned up after themselves. They made sure I was comfortable and that I was happy with there work. I will definitely be contacting them for all my future handy work."

FAQs for addition and remodeling projects in Sag Harbor, NY

The proper sequence of a kitchen installation starts with laying the foundation and structural framework. From there, you need to establish utilities like plumbing, wiring, and gas lines, then install cabinetry and countertops, and finally finish with flooring, painting, tile backsplashes, and lighting. A professional kitchen installation contractor can coordinate each component of your project to minimize the timeline and maximize resources.
